Assessment methods and Criteria
The exam is made of two parts, a written test and an oral test.
In the written test, the student will solve three problems on (1) an electrical circuit in dc, (2) a transistor amplifier, and (3) an active filter or an amplifier circuit employing an op-amp; the time for the written test is three hours.
In the oral test, the student will be asked questions on the structure, the operation, and the electrical models of the main solid-state electronic devices (diode, BJT, MOS transistor), and on the CMOS logic circuits.
